Going undefeated in a season is one of the hardest things to do in college football. That is especially true over a 12 or 13-game schedule against highly competitive opponents, which is the case for teams in one of the Power Five conferences.
Among teams that currently make up the Football Bowl Subdivision, only eight teams have ended the season with a perfect record in the last decade. And only six of those undefeated seasons were produced by Power Five teams. In four of those years, no FBS team ended the year undefeated.
Oklahoma’s 14 undefeated seasons in 123 seasons of varsity college football ranks fourth all-time, according to NCAA Division I football records.
